A jig is a device that drives pulses of water upwards through a thick bed of settled sediment in order to keep it loose and agitated. This achieves gravitational separation by allowing the denser minerals to sink easily and quickly through the lighter minerals. A typical jig consists of a water-filled tank known as a jig-cell, with a horizontal.
